Implication

Comparative study reveals altered mitochondrial morphology and axon fragmentation in animal brain tissue, highlighting trade-offs between histology quality and animal welfare.

Key Points

Post-mortem perfusion impairs structural integrity relative to transcardiac delivery, producing fragmented axons and altered mitochondrial morphology across fragile brain structures.
Variable immunostaining intensity and altered marker expression patterns occurred across evaluated tissue groups, directly reflecting fixative agent choice and delivery timing.
Comparative study across multiple tissue fixation protocols evaluated dendritic spines, axonal integrity, and cerebral histology under transcardiac or post-mortem perfusion.
